I think you completely skipped dover a few things.
Firstly, it is comparable. Hard ticket event or not, it is still park admission. She very clearly stated that yes an alternate date was offered, but if you couldn't change your date, they would not offer a refund (that she is aware of). They were kind enough to apply the amount as credit towards another admission product, but they didn't just hand people back their money. Maybe I got that wrong, but I'm pretty sure that is what she was getting at?
Secondly, yes there is no park that offers a pass with no blackout days that requires a no show deposit. You know why? Because this is an entirely new situation and a chain of parks has decided to try something new. *Gasp* It's new ... something that has never happened before. I know it is scary stuff. But guess what, maybe this will be necessary for their operations to work smoothly? Clearly, someone who works for a theme park chain thought, this might be a good idea to help with social distancing. That said, Six Flags hasn't said if they are requiring deposits for reservations.
So yeah, this is a new situation and parks are going to get creative on how they handle admission especially with such restrictions. Right now, there is very little information because this is still an active situation and closure for parks. Things haven't been fully announced, and things are still fairly fluid until they are announced. All this talk is solely about concepts, and shouldn't be taken as definite information.
